  6.   * CALCULATE RETAIL PRICE
  7.   *_______________________________________________________________
  8.   * This program computes the retail price of an item based on
  9.   * its wholesale cost and markup percentage.
  10.   *
  11.   * Computation is based on the formula:
  12.   * Retail Price = Wholesale Cost +
  13.   *                (Wholesale Cost * Markup Percentage / 100)
  14.   *_______________________________________________________________
  15.   * INPUT
  16.   *   wholesaleCost  : Wholesale cost of the item
  17.   *   markupPercent  : Markup percentage of the item
  18.   *
  19.   * OUTPUT
  20.   *   retailPrice    : Retail price of the item
